GAS-IIEATED "SAID-IRON.

Specification of Letters Patent.

Patented Oct. 2S, 1913.

Application filed May 15, 1913. Serial No. 767,863.

purpose of heating the same, and the object of my invention is to provide a simple and improved construction of iron which will permit an abundant supply of air to enter the body of the sad iron for the purpose of supporting combustion, and in which the parts are so constructed and arranged that the iron can be moved back and forth or in any direction without creating any suction.

Another object of the invention is to provide an iron of such construction that all danger of escaping gas due to a partial noncombustion is entirely avoided.

With these and other objects in view as will appear hereinafter my invention con sists in the novel features of construction hereinafter fully described and pointed out in the claims.

In the drawings forming a part of this specification: Figure 1 is a vertical longitudinal sectional view of a gas heated sad iron embodying my invention. Fig. 2 is a top plan View with the cover plate removed. Fig. 3 is an end view. Fig. l is a transverse vertical section on the line 1 -l of Fig. 2.

In carrying out my invention I employ a hollow sad iron body A of suitable size and shape, the sides and bottom thereof being imperforate, except that the sides are out away slightly at their upper edges as shown at A and the rear end is also cut away at definite points along its upper' edge as shown at A2.

Any suitable form of cover B is attached to the top of the body portion by screws at the front and rear ends, and to this cover is attached the usual or any approved form of handle C.

The rear end of the body portion is formed with a central opening D through which the burner pipe E is passed, said burner pipe having a series of jet openings E' produced in the bottom thereof. This burner pipe at its rear end is connected with the usual gas tube and is provided with air inlet openings according to the usual man near `of Bunsen burners. This burner or pipe E is positioned within the hollow body ya suitable distance above the bottom thereof and extends the entire length, the forward end of the burner pipe being screwed into a threaded recess F produced in the forward end of the hollow body. This closes the end of the burner pipe and also provides the proper connection of the pipe to the iron.

The bottom of the body A is formed with an air channel Gr which is open at its rear end and extends substantially the entire length of the sad iron body terminating at a point Gr adjacent the forward end of the sad iron body. This air channel G is formed' by eoring out, and at the same time I preferably eore out air reservoir recesses E2, upon each side of the main channel G and communicating therewith, these reservoir passages extending out to the front of the iron and terminating in openings G3 adjacent the point of the iron, the recesses E2 having oblique walls Gr4 which serve to contract t-he size of the openings G3 and also cause the air to enter not in a direct line but slightly at an angle or deflection. The reservoir recesses E2 do not extend entirely to the rear end of the iron but are terminated. by a wall G5.

It will thus be understood that I provide a hollow sad iron body in which the burner pipe is arranged and the bottom of this sad iron body has an air channel extending longitudinally therein from the rear end to a point very near the forward end of the sad iron and communicating with the central passage are the side reservoir passages which are slightly contracted at their forward ends and open to the atmosphere adjacent the point of the sad iron. l

By means of a sad iron constructed in accordance with the drawings and above description I am able to provide an abundant supply of air to the burner and at the same time I am able to move the iron forwardly, rearwardly or to either side and in quick action without producing any suction or without cutting off any of the air supply. The air entering at the forward end passes into the reservoir space upon both sides of the central passage with the advantageous results above referred to,

What I claim is l. In a sad iron, a hollow body having a burner pipe arranged therein, the bottom of said hollow body having an air passage arranged centrally and longitudinally thereof, said central air passage having opposite-ly disposed forward passages communicating therewith substantially as described.

2. In a sad iron, a hollow body, a burner pipe positioned in said hollow body, the bot.- toin of said body having a central air passage arranged longitudinally therein and eX- tending from the rear end thereof to a point adjacent the forward end and side passages upon each side of the central longitudinal passage and communicating therewith, said side passages being open at the front as set forth.

3. In a sad iron, a hollow body, a burner pipe positioned in said hollow body, the bottorn of said hollow body having a Central longitudinal air passage extending from the rear end thereof to a point adjacent the forward end, and passages upon opposite sides of said central air passage, said side passages extending to the forward portion of the iron and terminating in contracted openings substantially as described.

4f. In a sad iron, a hollow body having an air channel arranged centrally in the bottom thereof and extending from the rear end to a point adjacent. the forward end, and side passages extending from points adjacent the forward end of the iron to points adjacent the rear end thereof, said side passages cominunioating with the central longitudinal channel.
